About The Project

The client required 200 sets of a milled aluminum case, anodized and fully-finished but not too expensive. Since we specialize in low-volume custom orders like these, we were able to deliver a complete set of parts (cover, housing, and activating lever) for less than they could get in Germany.

About The Client

Snuffmachine was founded in 2007 in the black forest region of Germany. Company owner Alexander Gerspach wanted to create a new product which was not available on the market – a dosage machine for nasal tobacco, or snuff.

About The Product

Snuffmaster is a snuff machine, snuff box and snuff dispenser in one single, practical and stylish device. By pressing a button, the Snuffmaster loads a premeasured dose of snuff from a storage tank into a dispensing chamber. It also allows direct snuffing, as well as an exact dosage of the snuff on the back of the hand.

CNC Machining

We chose 6061-T6 aluminum for the main parts. This is a commonly available aluminum alloy that machines well, is not too expensive and looks great after anodizing.

Also, aluminum is lightweight, making the Snuffmaster easy to carry in a pocket or bag. A 3-axis CNC mill is used to route the profile of the case.

Sandblasting

After milling there were some fine machine marks and scratches on the metal. To remove these, all of the parts needed to be placed in a sandblasting chamber and carefully sanded with a fine grit. This gives the parts a uniform matte finish and removes any burrs.

Anodizing

Sandblasting provided the ideal surface texture for accepting the anodizing process. After a thorough cleaning, parts were placed on trees to keep them separate and then dunked into a chemical tank. This is a passivation technique that adds color while increasing corrosion and scratch resistance. And of course it looks great too.
